EP HiBuild Primer is intended for industrial applications; either new build or maintenance. EP HiBuild Primer is suitable for application on steel, aluminum, stainless steel, fiberglass, other ferrous metals and fiberglass reinforced plastics. This primer must be topcoated to achieve the best results.
Industrial Applications:
- Offshore Drilling Rigs
- Pulp Mills
- Chemical Plants
- Boats
- Bridges
- Marine
This primer is not suitable for automotive applications.
- Mix Ratio
- 4 part by volume of component A
- 1 part by volume of component B
The recommended temperature when mixed is 68-77°F (20-25°C).
- Surface Preparation
Surface must be free of all contaminants such as dust, oil, grease and salt. It is recommended that all steel and other ferrous surfaces be sandblasted a minimum of SSPC-SP6 or mechanically sanded with 40 grit sandpaper.
Note: For use on fiberglass or wood boat hulls, machine sand with 80 grit sandpaper. A minimum of 10 mils (250 microns) dry film thickness is required for waterproofing. Endura EX-2C Topcoat is not recommended below the waterline.
- Application Method
EP HiBuild Primer can be applied using most spray systems, although electrostatic sprayers are not recommended. Apply 2-3 coats as required to achieve the desired film thickness. Allow sufficient flash time between coats especially with higher film builds applied (20-30minutes).

-
Note: Spraying viscosity and thinning will depend on ambient conditions, spray equipment used, and the desired surface finish.
If required, recommended spraying viscosity is achieved by reducing with one of the following Endura Low VOC Epoxy reducers. These will maintain VOC compliance of EP HiBuild Primer.
VOC content of the following Reducers: (0g/l, 0 lbs/gal)
[FTH0016] Low VOC Epoxy Reducer- Regular
[FTH0027] Low VOC Epoxy Reducer- Slow
- Film Build
EP HiBuild Primer has a recommended film build thickness of:
WFT (Unreduced) 5.5 - 8.0 mils 140 - 203 microns
DFT 4 - 6 mils 102 - 152 microns
WFT (Unreduced) 13.6 mils + 345 microns
DFT 10 mils + 254 microns
The recommended dry film thickness is above the blast/sanding profile.
Theoretical coverage at 1.0 mil (25 microns)
DFT: 1173 ft² per gallon at 100% transfer efficiency.

For best results surface temperature must be 86°F (30°C) or less before top coating. Maximum re-coat window without sanding is 24 hours at 68°F (20°C) Recommended Sanding 180 - 220 grit after the topcoat window has been exceeded.
- Top Coating Infomation
EP HiBuild Primer can be topcoated with the entire range of Endura topcoat products.
- Clean Up
Clean all equipment immediately after use with Endura High Strength Gun Wash, Endura epoxy reducer or Endura EX-2C thinner.

Safety & Health
- Environmental Conditions
For optimum coating performance, product, substrate and ambient temperature should be between 68°F-77°F (20°C-25°C). To prevent condensation during application the surface temperature must be 5°F (3°C) or more above the dew point at all times.
